Fuuka is the true name given by Tonbo's soul within Kano's mental landscape. It is unclear how independent the two are. Fuuka may be more than just Tonbo's soul and actually also contain the other 1000 souls meant to be absorbed in the Ritual of Bonding. Fuuka reveals to Kano that the interrupted ritual left some of Fuuka's/Tonbo's soul in her body and robbed Tcaolin of much of her power and that killing her Champion would kill Tonbo/Fuuka, leaving Tcaolin without a potential vessel.
